This "conflicts" with XSL-FO which can force spaces being retained
therefore adjustments to the algorithm are necessary to cater for that.
Computing line breaking opportunities and discarding whitespace at the
end (or beginning) of a line are different matters. If whitespace has
to be retained, trailing spaces after a non-space string may simply mean
the previous line breaking opportunity has to be used, because otherwise
the string including the trailing spaces will overflow the line area.
The trailing whitespace may also influence text justification.
